چکیده مقاله:
Buckling-restrained braces (BRBs) are the special type of braces used in lateral force -resisting systems in structures. The shape-memory alloy (SMA) rod which uses along with the BRB is relatively costly, to optimize the use of SMA rod along the BRB with effective re-centering. The evaluation of present study is focused on the seismic response of BRBFs with shape memory alloy-based under the near -field ground motions. In order to examine the performance of suggested system, a 4-story steel frame is modeled and Incremental Dynamic analyses are conducted to investigate the effect of SMA on the response of the structure.
